Spanning bipartite quadrangulations of triangulations of the projective plane
Kenta Noguchi
文献摘要
We completely characterize triangulations of the projective plane that have a spanning bipartite quadrangulation subgraph. This is an affirmative answer to a question by Kündgen and Ramamurthi (J Combin Theory Ser B 85, 307–337, 2002) for the projective planar case.
